Method to return the equation of a straight line given two points in python

Method to return the equation of a straight line given two points in python

To find the equation of a straight line given two points in Python, you can use the slope-intercept form of a linear equation: y=mx+by = mx + by=mx+b, where mmm is the slope and bbb is the y-intercept. Here's how you can calculate and return the equation of a straight line using two points:

def equation_of_line(point1, point2): x1, y1 = point1 x2, y2 = point2 # Calculate the slope (m) slope = (y2 - y1) / (x2 - x1) # Calculate the y-intercept (b) using the equation: y = mx + b y_intercept = y1 - slope * x1 # Return the equation in the form "y = mx + b" return f"y = {slope:.2f}x + {y_intercept:.2f}" # Two points point1 = (2, 5) point2 = (5, 12) # Calculate and print the equation of the line equation = equation_of_line(point1, point2) print(equation)

Replace point1 and point2 with your own points. The equation_of_line() function calculates the slope (mmm) and the y-intercept (bbb) using the given points and then returns the equation of the line in the slope-intercept form.

Keep in mind that this method assumes a non-vertical line (i.e., the denominator x2−x1x2 - x1x2−x1 is not zero). If you need to handle vertical lines, you'll need to use a different approach.
